To a/ZZ whom t may concern.-

Be it known that I, WILLIAM N. HARING, of Nyack, in the county ofRockland and State of New York, have invented a new and usefulImprovement in Car-Couplings, of which the l following is aspeciication.

My invention relates to an improvement in car-couplings in whichprovision is made for the locking of the coupling-heads together eitherautomatically or by hand and in which the heads may be released eitherby drawing upwardly directly upon the locking-pin or elevating it by anindirect attachment from the side.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure 1 is a top plan view of one ot'the coupling-heads and the parts which support it. Fig. 2 is ahorizontal section through the draw bar and head. Fig. 3 is a view ofthe same in side elevation, showing, also, one of` the side supports anda portion of the buffer; and Fig. 4. is a vertical transverse sectionthrough the coupling-head on line wx of Fig. l.

The supporting-beams between which the coupling is mounted arerepresented by A and A', and they are connected at or near -their frontends bya bader-beam a, (see Fig.

3,) to the front of which a buffer Bis securedin the present instance bymeans of bolts b, extending through the buer-beam. Between the saidbeams A and A there is iixed a heavy bracket O, the forward end of whichis bifurcated to receive between its lugs c the head d ofthe plunger D.A heavy cross-bolt c extends through the lugs c and the head d of theplunger to secure it to the bracket O. The plunger rod or stem isdenoted by d and it has mounted thereon the end washers d2' The plungeris locked Within the socket in the draw-bar E by means of keys e', whichextend downwardly through the rear end of the draw-bar, upon oppositesides of the plunger, as clearly indicated in Figs. l and 2, and formabutments for the end washers d2, so that when the draw-bar Eispulledoutwardly it will slide the washer d2 on the stem of the plunger, andthereby compress the springs d5 and d6. The limit vof the outwardmovement of the draw-bar is determined by the engagement of the shouldere2 on the under side of the draw-bar with the fixed cross-bar a', boltedor otherwise secured to the under sides of the supports A and A. Thedraw-bar E is held in position between the supports by means of across-bolt c2, extending through the supports A and A and through anelongated slot e3 in the side of the bar. The washer d3 abuts againstinternal shoulders e4 within the drawbar, and when the draw-bar E isforced inwardly it carries the washer d3 with it, and thereby compressesthe springs d5 and d6. The limit of the inward movement of the draw-baris determined by the engagement of shoulders on the coupling-head withthe front of the buffer B.

The body portion of the coupling-head or draw-head is represented by F,and it is provided with a hinged jaw f and a stationary jaw f', betweenwhich the hinged jaw of the opposite coupling-head is received when 'thetwo are brought together into interlocking adj ustment.` The head F hasextended rearwardly therefrom a stem f2, (see Fig. 2,) adapted to seatwithin a socket e5, formed in the front end of the draw-bar-E, and issecured therein by means of a coupling-pin G, extending downwardlythrough the draw-bar and the stem f2, so that if from any cause thedraw-head becomes useless it may be removed and an ordinary link-and-pinlattachment may be made directly with the front end of the draw-bar. Thehead F is provided with a socket f?, extending transversely therein, andin said socket there is seated a sliding bar II. The projection f4 onthe swinging jaw f projects within the socket f3 and seats looselywithin a recess h, formed in the front of the bar H, so that as the jawf opens and roo closes on its pivot to release or lock the correspondingjaw on the opposite draw or coupling head it will slide the bar Hinwardly or outwardly in the socket f3, and if the bar H be lockedagainst an inward movement it will thereby lock the head F againstswinging outwardly to release the corresponding jaw of the draw-head. Alocking-pin g is seated within the head F so as to have a limitedvertical movement therein and is adapted to drop downwardly through anopening h' in the bar H when the latter is at the limit of its outwardmovement, and thereby lock it againstinward movement until the pin g iswithdrawn. The pin g has a guiding-prong gthereon,ex tending downwardlythrough the head F, and is iitted at the top to receive an operatingchain or cord. The pin g may also be operated bymeans of an angle-leverpivotally secured to the head, as at I, one arm 1l of said leverextending within the head and loosely engaging within a recess g2 in theside of the pin g and the other arm i being fitted for the attachmentthereto of an operating-chain K, leading to the side of the car. Bypulling upwardly on the pin g by a cord or chain attached to its top andleading, for example, to the top of a freight-car the bar H may bereleased and the jaw f thereby allowed to swing outwardly and uncouple.By pulling outwardly on the chain K the. angle-lever, pivoted at I,willrock in a direction to lift the pin g, and thereby release the bar H andpermit the jawf to swing and uncouple. As two opposite draw-heads cometogether the jaws f will be swung simultaneously inwardly, and the bar Hwill thereby be moved outwardly until the pin g drops under theinfluence of gravity through the bar H, and thereby locks the couplingstogether. In case the pin gshonld become broken or jammed, so that itcould not be utilized to lock the bar H in its outward adjustment, Iprovide for locking it in such position by hand by forming a perforationh2 downwardly through it near its outer end for the purpose of receivingan ordinary coupling-pin. The free end of the jawfis bifurcated andprovided with the perforation f5 therethrough to receive the ordinarylink and coupling-pin, as is usual.

Nhat I claim isl. The draw-head comprising a body portion, a swingingjaw secured thereto, a coupling-pin, and a sliding bar having alooseconnection with the swinging jaw and couplingpinto lock and release thejaw when the bar is locked or released by the pin, substantially as setforth.

2. The draw-head comprising a body portion, a swingingjaw securedthereto, a laterally-sliding bar having a loose connection with theswinging jaw, a locking-pin having a limited movement into and out ofengagement with the sliding bar, and a lever having a loose engagementwith the locking-pin for operating it and hence releasing the bar,substantially as set forth.

3. The combination, with the draw-barand draw-head secured thereto, of aplunger inserted within the rear end of the draw-bar, a bearing on theplunger, and keys extending downwardly through the draw-bar inengagement with the bearing forlocking the plunger therein in removableadjustment, substantially as set forth.
